Abstract:To investigate the effect of hard segment content on ionic conductivities of poly(ether urethane) (PEU)-based solid polymer electrolytes (SPEs), PEUs containing 20, 40, 60, 80, and 100 wt.% of hard segment content were synthesized. Also we introduced polymer-in-salt system with ion-hopping mechanism contrary to traditional salt-inpolymer system with segmental motion mechanism and investigated the effect of hard segment of PEU on ionic conductivities by A.C. impedance, FT-IR, DSC, and SEM. And it could be known… Show more
“…S6b†), which is much higher than that of the PCA-PE and PCL-PE and is important to improve the energy density of batteries. 42 t Li + plays a key role in the electrolyte evaluation. According to Fig.…”
Polymer electrolytes (PEs) are promising for constructing solid-state batteries with high energy density due to the great flexibility and high processability. However, it is difficult to construct such a system...
